Nothing says all-American bombshell like lush, long locks — and these stars have it down to a science. Watch and learn.

"I am a fan of this style," says Kristen Bretz, a stylist and manager at Brooklyn's Hair Metal Salon and an educator/color specialist for Keratin Complex. "The spot where the hair begins to wave is perfect. Kerry has an oval face shape and high, prominent, beautiful cheekbones. This is played off of nicely by the initial bend away from the face, which opens up the space and draws attention to her eyes and cheekbones."

Kate's just-in-the-middle waves look cooler that top-to-bottom bends. Bretz suggests taking a curling wand to straight, blow-dried hair. (The clamp of a curling iron can leave a line). Apply a curl cream, then divide hair into small sections. Starting one-quarter to halfway down the hair, wind sections around the wand, leaving a few inches at the end straight and spritzing with hairspray or working spray to set. Then gently shake out or comb hair with your fingers to get the desired level of wave.
